SPECIFICATION forming part f Letters Patent No. 587,261, dated. July 27, 1897. Applieation led February 13, 1893. Serial No. 462,044. (No model.)

To all wil/0712. it nung/ concern:

Be it known that I, FREDERICK GEORGE JAHN, of Brooklyn, in the county of Kings, in

the State of New York, have invented newand useful Improvements in Printing-Dies, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in markers particularly applicable for use with machines for post-markin g and stamp-canceling mail-matter, and has for its object the production of a simple and economical device which is practical, efficient, and convenient in use; and to this end it consists, essentially, in a type-carrying section mounted on a suitable support, as a rotary roller, and provided with a projecting type-carrying portion having a series otpermanent type arranged on its face and formed integral therewith and having a socket in its central portion, and a type-carrying block removably mounted in said socket and having on its face a series of type formed integral therewith.

The invention furthermore consists in the detail construction and arrangement of the parts of myinvention, allas hereinafter more particularly described, and pointed out in the claims. l

In describing this invention reference is had to the accompanying drawings, forming a part of this spec-ilication, in which like letters indicate.' corresponding parts in all the views.

Figure 1 is a top plan view, partly in section, of an ordinary form of marking-roller for post-marking and stamp-canceling machines. Fig. 2 is a sectional view taken on line 2 2, Fig. 1, representing particularly the marker and the removable type-carrying box for the marking-roller shown at Fig. 1. Fig. 3 is an inverted top plan view, partly in section, of my improved marker, shown as operatively secured to a marking-roller suitable for a machine for post-marking and stamp-canceling mail-matter. Fig. 4 is an outer face view of the detached marker, shown at Fig. 3 as operatively mounted upon a supportingroller. Figs. 5 and 6 are respectively vertical and horizontal sectional views taken on lines 5 5 and 6 6, Fig. 4, the marker being inverted at Fig. 5. of the detached catch for holding the removable type-carrying block in position. Figs. 8 and'9 are, respectively, front or outer face view and top plan or edge View of the detac-hed type-carrying block. Fig. 10 is an isometric perspective of a detached block or plate secured to the type-carrying section of my marker for engaging the type-carrying block. Fig. 11 is a face view of the print or impression produced by a marking-roller provided with my improved marker, as shown at Fig. 3. Fig. 12 is a top plan view, partly in section, of a marking-roller provided with a slightly-different construction of my invention. Fig. 13 is a top plan view of the de tached marker shown at Fig. 12. Fig. 14 is a vertical sectional view taken on line 14 14, Fig. 13. Fig. 15 is an outer or front face elc- Fig. 7 is an isometric perspectivevat'ion of the detached base of the type-carryl In order that mypresent invention maybe clearly understood, I have here illustrated, at Figs. 1 and 2, and will now briefly describe, a well-known form of marking-roller for postmarking and stamp-canceling machines.

A represents the body or frame of a rotary marking-roller, which is mounted on a revoluble shaft a, journaled in any suitable support. (Not here illustrated.)

B B are a series of bars of narrow cross- -section which are arranged one above the other upon a portion of the peripheral face of the frame A and are secured in position by suitable post-s b.

O is a type-carrying section secured by suitable fastening means c to a portion of the frame A in proximity to the bars B B. This type-carrying section is formed withV a cen- IOO tral opening C, extending through its central portion, and is provided on its outer face with a series of type c for printing an impression representing the name of the city or town in which said marker is used, the State containing the city, and the number of the year when the marker is used.

D is a wed (ge-shaped box formed with a central cavity D', in which are removably secu red a series of changeable type D2 for printing an impression representing the month, the day of the month, and the hour of the day when the impression is made. Two of the opposite sides of this box D are necessarily radial, as shown at Fig. l, and consequently two sides of the type D2 are also radial, and, as best seen at Fig. 2, the box D is formed with a partition D3.

rlhe type are arranged in two rows between the partition Diand the adjacent walls of the box D and are held in position by keys d cl, onevof which is movable in a groove d2 in 'the wall of the box D and in grooves (Z3 in adjacent faces of the type D2. The other key d' is movable in a groove d4 in one side of the partition D3 and in grooves d3 in the adjacent sides of the type D2. A spring D4, having one end secured to the frame A by a suitable screw d5, bears against the inner face of the box D and tends normally to force the same from operative position. A second spring-catch D5 is formed with a shoulder D6, which engages a shoulder DT on one of the outer sides of the wall of the box D for holding the box in its normal position against the action of the spring D4.

As is evident to one skilled in the art, it is highly essential that the impression printed by the marker of a stamp-canceling and postmarking machine be perfectly7 legible and clearly defined, as it is frequently called into question and as legibility and clearness are requirements of the Post 'Office Department. This result can be obtained only with the best conditions and by uniform type having y their faces uniformly engraved and disposed when printing in the same plane.

It is also well known to those skilled in the art that it is almost impossible to obtain engraved type which are uniformly engraved and are so relatively arranged as'to assume the same plane when printing,especiall`y when said type are separable one from the other. As the type for a marker used with stampcanceling and post-marking machines are ordinarily, as illustrated at Fig. l, formed with their type-carrying faces disposed in a curvilinear plane and are supported by a rapidlyrevolving frame or die, a clear and well-deiined impression can be obtained only when the type are un usually uniform. Moreover,as in the construction of marker shown at Figs. l and 2, the type are formed separable and are itted Within a type-containing box and are necessarily provided with two inclined sides. Unusual care and skill must be used in order that the type, even though absolutely uniform, may fit properly within the type-carrying box and against each other, so as to produce a legible and well-defined impression. The diculty occasioned in obtaining type suitable for practical and effective use on a marker of this character is further increased from the fact that the typecarrying face of the marker is disposed in a curvilinear plane, and therefore the outer face of each type must be cut for the particular place upon the marker which said type is designed to occupy.

It is evident to one skilled in the. art that the type for making an impression representing the naine of the city, the State containing the city, and the number of the year are not changed until worn out, as it is very seldom that the type will last a whole year, and that should said type last a whole year they are then replaced upon the commencement of a new year. On the contrary, the type 'for making 'the impression representin g the month, the day of the month, and the hour of the day must be changed, respectively, once a month, levery day, and every hour or half-hour. It is also customary to use after the type for making an impression representing the hour type provided with characters for printing p. m. and a. 111., and one of these type is necessarily changed twice a day. Consequently, asthe type for representing the day, the day of the mouth, and the hour of the day are changed at unequal intervals they become unequally worn, and while one type may make a clear and well-defined impression the impression made by another type is hardly legible. It requires considerable care, experience, and time to properly change the type of a marker and suitably arrange said type to remain in Jthe required position and print a clear and welldefined impression, and it is usuallythe case that at the very hour when the type are to be changed the machine is required for use to its full capacity. Markers formed of this construction are extremely expensive and are also very perishable, as the walls of the type-carrying box are necessarily thin and are more or less fragile. A great number of type are lost in cutting, since it is iirst necessary to bring the same to the required dimensions, and if the engraver carelessly or inadvertently decreases the length of the type by cutting away its end in forming the character thereon the same is rendered entirely Worthless.

My present invention has for its object the production of a marker which is more cconomical, practical, effective, and convenient than the previously-dlescribed construction, and I will now proceed to describe the same.

E represents the type-carrying section of my improved marker, which is secured to a suit-able support, as the frame or body F of a marking-roller secured upon a revoluble shaftf, j ournaled in a suitable support. (Not here illustrated.) The frame or body F is lOO IIO

'formed with a suitable cutout F, alined with the type-carrying section E, and is provided upon a portion of its peripheral face with a series of bars F2 of narrow cross-section, arranged one above the other in proximity to the marking-section E, for printing the characters orlin es g of the impression G, produced by the marking-roller for canceling the stamps upon' the mail-matter. The bars F2 are held in position by suitable posts f.

The type-carrying section E extends transversely across the face of the support or roller F, and its outer face is disposed in a curvilinear plane substantially concentric with the shaft f, and is provided With a projecting type-carrying portion E. 4

e e' are a series of type arranged in proximity to the projecting portion E', and e2 is a ring or flange at the edge of said projecting portions E'. The type e and the ring e2 are preferably formed integral With the type-car rying section E, which is preferably formed of hardened cast-steel, and said type and ring Aare produced by engraving the outer face of the projecting port-ion E of said type-carrying section E. The type e' are provided With characters suitable for making the characters g of the impression G, Fig. 1l, representing the namev of the place and the State in Which the marker is used and the number of the year during which itis used-as, Syracuse, N. Y., 1893.

e3 is a socket in the central part of the projecting portion E of the type-carryin g section E, and, as best seen at Figs. 3, 5, and 6, this socket is formed with an inner Wall e1, having a pair of perforations e5 e0 therethrough, arranged one above the other.

c7 is a block or plate removably secured by suitable fastening means e0 in the upper end of the socket e3, and e0 is a shoulder provided upon one edge of said block.

Removably secured in the 'socket es is type-carrying block H, having its outer face disposed in a curvilinear plane substantially concentric with the plane of the typecarrying section E and provided With type h 7L, arranged alongside of each otherin tWo rows, one above the other. type-metal, which it is evident is softer than the material composing the type-carrying section, and the type h h are formed integral with said block H when said block is cast. The type 7i, form the characters-g2 of the impression G, Fig. 1l, for representing the month, the day of the month, and the hour of the day When the marker is used.

The removable type-carrying block H is formed on one edge with a shoulder H for engaging the shoulder e9 of the block or plate e1' and is provided on the other edge with the opposite shoulders of a groove H2, With which is engaged the spring-arm t' of a catch I. .This

' catch consists, preferably, of a base t', secured by suitable fastening means 112 i2 to a block I', and a spring-arm t', having its outer end passed through theperforation e0 in the Wall The block H is formed of castY e4 of the socket e3 and provided with a shoulder t2 for engaging the shoulders of the groove H2. The block I is secured to the inner side of the type-carrying section E by suitable fas- `The removable type-carrying block H is ejected from operative position by an ejecting-piece, Which consists of a plunger J, movable in a guide I3 in the block I, and a spring QV, mounted in the guide I3 and bearing against the plunger J. The outer end of the plunger J projects through the perforation e5 in the Wall e1 of the socket e3 and is provided With a stop-shoulderj. When desired to remove the type-carrying block H, the shoulder i3 ot' the spring-arm i' of the catch I is forced downwardly out of enga-gern ent with the shoulders of the grooveH2, whereupon the plunger J of the ejecting-piece immediately forces said block H out of the socket e3 in the type-carrying section E.

At Figs. 12 to 20, inclusive, I have shown a different construction of my invention, in which the type-carrying section E10 consists of a base E11, mounted upon a suitable support or roller G10, and a type-.carrying portion E12, provided on its face with type @10, similar to the type e'. This type-carrying'portion E12 consists of a hollow cylinder movable through an opening E13 in the base E11, and itis secured in position by a suitable screwc, passed through the Wallof v"the base E11 into the typecarrying cylinder E12. Vithin the type-carryin g cylinder E12 is a cylindrical support E15, provided with an engaging shoulder E16 for IOO IIO

engaging one or more shoulders H11, formed upon an upper edge of a type-carrying bar H10 of similar construction to the bar H, previously described. This cylindrical support is secured in operative position by the screw lo, previouslyqmentioned, which passes through the Wall of the -cylindrical type-carrying section E10 into a socket provided in said cylinder or support E15. The catch for holding the type-carrying block H10 in its operative position consists of an arm having one end suitably secured to the support E15 and the other formed with a shoulder 00 for engaging va shoulder H20,upon one of the edges of the block H10. The eject-ingpiece for discharging the block H from its cylindrical support E15 consists of a spiral spring J 10, movable in a socket in the central port-ion of said support E15 and arranged with one end normally bearing against the inner face of said block H10.

From the foregoing description of my present inventionr it lWill be readily understood that I forni the type for printing the impression representing the city, the State, and the year upon a hardened-steel section by engraving the type in a portion of the outer face of said section, and thatlform the type forprinting the impression representing the month, the day of the month, and the hour upon the outer face of a block cast or otherwise formed of soft metal and having the type formed integral therewith. After the mastentype for producing the type upon this block are once cut the c'ast block is very inexpensive. All

- of the type thereon are uniform, and when desired to change one of the type the entire block is thrown aside and may, if desired, Abe remelted for forming additional blocks.l

In practice a number of blocks having type suitable lfor all of vthe changes required for a certain limited time, as a month or a year, are formed, and these are then arranged upon a suitable support or ribbon, (not necessary to herein illustrate,) and when desired one of the blocks is easily removed and replaced by another, which is easily selected by the operator. The advantages of this peculiar construction of marker are obvious to one skilled in the art, since all of the movable type are mounted upon a single block, which is easily changed and is economically manufactured. Moreover, all of the removable type which print the most important part of the impression are worn uniformly and are used but a very short time, so that a legible and clear impression is produced at all times. No expensivetype-carrying box is required. There is no liability of an engraver spoiling expensive type, nor any liability of one type -projecting a greater distance than the other bei yond the `plane which should be occupied thereby when makingan impression. ,I have discovered upon practical experience, ho\ 1- ever, thatitis not desirable, nor, indeed, practical or possible, to form of cast metal the type e for printing an impression representing the name of the city or town and the State `provided with the marker therefor, as, owing to the constantly-varying plane occupied by the similar type for forming different .names and owing to the varying number of' let-ters in the namesof the various towns and cities, an incalculable number of master-type would be required, the faces of Awhich would be disposed in planes of dissimilar `curves representing the curve of the corresponding portion of the outer face of the type-carrying section to be provided with said type were it possible to make and practically arrange, use, and rearrange such a great number of ymaster-type, many of Which were provided with similar characters. a

It will thus be readily understood that my invention reduces to a minimum the amount of care, time, and skill at present required in attending to the marker of a stamp-canceling machine, greatly reduces the expense incidental to the manufacture and maintenance of said marker in operative condition, adds greatly to the legibility and clearness of the impression produced by the marker, and is .highly efficient, durable, convenient, and practical.

The operation of my invention will be readily perceived from the foregoing description and upon reference to the accompanying drawings, and it will be readily understood that :the same is not limited to the exact detailconstruction and arrangement of its parts.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
